properties of Riemann xi function
The Riemann xi function, defined by
ξ(s):= |
is an entire function having as zeros the nonreal zeros of the Riemann zeta function
and only them.
The modulus of the xi function is strictly increasing along every horizontal half-line lying
in any open right half-plane that contains no xi zeros. As well, the modulus decreases strictly along
every horizontal half-line in any zero-free, open left half-plane.
Theorem. The following three statements are equivalent.
(i). If is any fixed real number, then is increasing for .
(ii). If is any fixed real number, then is decreasing for .
(iii). The Riemann hypothesis is true.
